Description

Technical Field

[0001] This utility model relates to the field of temperature control equipment, specifically a self-heating memory. Background Technology

[0002] In the refrigeration cycle of a chiller, the load is dynamic, which causes the refrigerant demand in the refrigeration system to change constantly. In order to ensure stable operation of the system, a memory is needed to adapt to the dynamic changes of the system under different loads.

[0003] In the prior art, traditional refrigerant storage devices store ordinary refrigerants in a liquid state at low pressure. However, carbon dioxide refrigerant needs to be stored in a supercritical state. In this state, carbon dioxide refrigerant has a density close to that of a liquid but maintains a high pressure. However, since the critical point of carbon dioxide is close to room temperature, traditional storage devices require additional heating measures to operate at room temperature, which inevitably increases the overall energy consumption. Otherwise, if the temperature cannot be provided above the critical point of carbon dioxide refrigerant, the refrigerant is prone to liquefaction, thereby reducing the pressure and failing to maintain the supercritical state of carbon dioxide. Therefore, this utility model proposes a self-heating storage device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a self-heating memory to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-heating storage device, comprising: a compressor, a storage tube connected to the compressor pipe, a U-shaped tube disposed inside the storage tube, one end of the U-shaped tube being connected to the compressor, an inlet and outlet pipe installed inside the storage tube, and a first solenoid valve and a second solenoid valve installed inside the inlet and outlet pipe.

[0006] Preferably, a mounting plate is fixedly installed at the lower end of the compressor, and a plurality of mounting holes are opened on the surface of the mounting plate. A first connecting pipe is connected between the upper end of the compressor and the storage pipe, and an inlet and outlet pipe is connected between the lower end of the compressor and the storage pipe.

[0007] Preferably, the storage tube has a rectangular parallelepiped structure, with a pressure relief hole on the side wall of the storage tube. A pressure relief pipe is fixedly installed in front of the pressure relief hole. Three sets of linearly equidistant mounting holes are provided at the lower end of the storage tube. The mounting holes at both ends are fixedly connected to the two ends of the U-shaped tube, and the mounting hole in the middle is fixedly installed with an inlet / outlet pipe.

[0008] Preferably, one end of the U-shaped tube is fixedly connected to a first connecting tube, and the other end of the U-shaped tube is fixedly connected to a second connecting tube.

[0009] Preferably, the inlet and outlet pipes have two branches, one of which is fixedly connected to the first connecting pipe and a first solenoid valve is installed between the branches, and the other branch is connected to the lower end of the compressor and a second solenoid valve is installed between the branches.

[0010] Preferably, the pressure relief pipe is located directly in front of the pressure relief hole, a sealing plate is installed inside the pressure relief pipe, a movable rod is fixedly installed on the surface of the sealing plate away from the storage pipe, an adjusting screw is fixedly installed on the end of the pressure relief pipe away from the storage pipe, an adjusting screw is screwed into the adjusting screw, a fixed bearing is provided on the outer wall of the adjusting screw near the sealing plate, the fixed bearing is fixedly installed on the adjusting plate, a movable groove is opened at one end of the adjusting screw, the movable rod can be inserted into the movable groove, a number of holes are opened on the surface of the adjusting plate, a limit rod is installed in the hole, a strong spring is provided between the adjusting plate and the sealing plate, and a number of pressure relief grooves are opened on the outer wall of the pressure relief pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The self-heating storage device proposed in this invention allows for efficient and energy-saving refrigerant management. When the system load decreases, the amount of refrigerant used in the system needs to be reduced. Excess refrigerant is controlled by a first solenoid valve to enter the storage tube from the inlet and outlet pipes. High-temperature carbon dioxide refrigerant is introduced into the U-shaped tube, thus storing the refrigerant in the storage tube in a supercritical state. When the system load increases, the system requires more refrigerant. By opening a second solenoid valve, the refrigerant in the supercritical state flows out of the storage tube and into the compressor, returning the refrigerant to the system. The system itself provides heat to maintain the supercritical state of the carbon dioxide, achieving efficient and energy-saving refrigerant management, reducing energy consumption and system complexity, and avoiding the problems of unstable refrigerant state and high energy loss in the storage device.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a self-heating storage memory, comprising: a compressor 1, a storage tube 2 connected to the compressor 1 by a pipe, a U-shaped tube 3 disposed inside the storage tube 2, one end of the U-shaped tube 3 connected to the compressor 1, an inlet and outlet tube 4 installed inside the storage tube 2, and a first solenoid valve 5 and a second solenoid valve 6 installed inside the inlet and outlet tube 4.

[0021] In operation, when the system load decreases, the amount of refrigerant used in the system needs to be reduced. Excess refrigerant is controlled by the first solenoid valve 5 to enter the storage tube 2 from the inlet / outlet pipe 4, and high-temperature carbon dioxide refrigerant is introduced into the U-shaped pipe 3, so that the refrigerant in the storage tube 2 is stored in a supercritical state. When the system load increases, the system needs more refrigerant. By opening the second solenoid valve 6, the refrigerant in the supercritical state flows out of the storage tube 2 and into the compressor 1, so that the refrigerant is transported back to the system. The system provides its own heat to maintain the supercritical state of carbon dioxide, which realizes efficient and energy-saving refrigerant management, reduces energy consumption and system complexity, and avoids the problems of unstable refrigerant state and large energy loss in the storage tank.

[0022] Example 2: Based on Example 1, a U-shaped tube 3 is provided to ensure that the storage tube 2 always maintains a high temperature. One end of the U-shaped tube 3 is fixedly connected to a first connecting tube 8, and the other end of the U-shaped tube 3 is fixedly connected to a second connecting tube 10. The inlet and outlet tube 4 has two branches. One branch is fixedly connected to the first connecting tube 8, and a first solenoid valve 5 is installed between the branches. The other branch is connected to the lower end of the compressor 1, and a second solenoid valve 6 is installed between the branches. A mounting plate 7 is fixedly installed at the lower end of the compressor 1. The surface of the mounting plate 7 has several mounting holes. The upper end of the compressor 1 is connected to the storage tube 2 by the first connecting tube 8, and the lower end of the compressor 1 is connected to the storage tube 2 by the inlet and outlet tube 4.

[0023] In order to keep the overall storage tube 2 at a high temperature, the first connecting pipe 8 is located at the outlet end of the chiller compressor 1. One end of the first connecting pipe 8 is fixedly connected to one end of the U-shaped tube 3 inside the storage tube 2. The outlet end of the compressor 1 continuously outputs high-temperature and high-pressure carbon dioxide gas into the first connecting pipe 8. The high-temperature and high-pressure carbon dioxide gas then passes through the U-shaped tube 3 inside the storage tube 2, thereby continuously heating the storage tube 2 and maintaining a high temperature inside the storage tube 2.

[0024] Example 3: Based on Example 2, a pressure relief pipe 9 is provided to improve the overall safety of the storage pipe 2. The pressure relief pipe 9 is located directly in front of the pressure relief hole. A sealing plate 11 is installed inside the pressure relief pipe 9. A movable rod 12 is fixedly installed on the surface of the sealing plate 11 away from the storage pipe 2. An adjusting screw tube 13 is fixedly installed on the end of the pressure relief pipe 9 away from the storage pipe 2. An adjusting screw 14 is screwed into the adjusting screw tube 13. A fixed bearing is provided on the outer wall of the adjusting screw 14 near the sealing plate 11. The fixed bearing is fixedly installed on the adjusting plate 15. A movable groove 1 is opened at one end of the adjusting screw 14. 6. The movable rod 12 can be inserted into the movable groove 16. The surface of the adjusting plate 15 has several holes, and a limit rod 17 is installed in the hole. A strong spring 18 is installed between the adjusting plate 15 and the sealing plate 11. Several pressure relief grooves 19 are opened on the outer wall of the pressure relief pipe 9. The storage pipe 2 is in the shape of a cuboid. The side wall of the storage pipe 2 has a pressure relief hole. The pressure relief pipe 9 is fixedly installed in front of the pressure relief hole. The lower end of the storage pipe 2 has three sets of linearly equidistant mounting holes. The mounting holes at both ends are fixedly connected to the two ends of the U-shaped pipe 3, and the mounting hole in the middle is fixedly installed with the inlet and outlet pipes 4.

[0025] To improve the overall safety of the storage tube 2, a pressure relief pipe 9 is fixedly installed on the side wall of the storage tube 2. The sealing plate 11 inside the pressure relief pipe 9 seals the pressure relief hole. At the same time, the movable rod 12 at one end of the sealing plate 11 is placed in the movable groove 16 of the adjusting screw 14, and a strong spring 18 is set between the sealing plate 11 and the adjusting plate 15. Under the action of the strong spring 18, the sealing plate 11 seals the pressure relief hole. When the pressure inside the storage tube 2 is too high, exceeding the force of the strong spring 18 on the sealing plate 11, the sealing plate 11 will move towards the adjusting screw 14 under the action of the movable rod 12, thereby relieving pressure inside the storage tube 2 through the pressure relief hole. This ensures that the pressure inside the storage tube 2 is always kept within a safe range. Furthermore, the force of the strong spring 18 on the sealing plate 11 can be adjusted by rotating the adjusting screw 14, thereby improving the overall safety of the storage tube 2.

[0026] In actual use, when the system load decreases, the amount of refrigerant used in the system needs to be reduced. Excess refrigerant is controlled by the first solenoid valve 5 to enter the storage tube 2 from the inlet and outlet pipes 4. High-temperature carbon dioxide refrigerant is introduced into the U-shaped pipe 3, so that the refrigerant in the storage tube 2 is stored in a supercritical state. When the system load increases, the system needs more refrigerant. By opening the second solenoid valve 6, the refrigerant in the critical state flows out of the storage tube 2 and into the compressor 1, so that the refrigerant is transported back to the system. The system provides its own heat to maintain the supercritical state of carbon dioxide, which realizes efficient and energy-saving refrigerant management, reduces energy consumption and system complexity, and avoids the problems of unstable refrigerant state and large energy loss in the storage tank.
